Eumeralla Formation

The Eumeralla Formation is a geological layer in southeastern Victoria composed of siltstone, sandstone, and claystone that spread across the Otway Basin. These rock layers preserve a record of how ancient river systems flowed and how the environment changed during that era.

This rock layer formed roughly 125 million years ago during the Early Cretaceous as Australia separated from Antarctica. Sediments accumulated over time and recorded this period of continental movement and change.

The formation attracts researchers who study early Australian life and document what creatures lived in this region long ago. Paleontologists continue to find and examine fossils that reveal details about these ancient inhabitants.

The formation lies below the surface and is studied mainly through scientific drilling and excavation rather than direct visitor access. Those exploring the region can see the landscape shaped by these deep rock layers.

Researchers have uncovered footprints and bones of dinosaurs within these layers showing that large reptiles roamed this region. Such finds are relatively rare in Australia and help scientists understand how different life was in various parts of the world.
